What is m∠2? °What is m∠1? °

Since the arrows indicate that those two lines are parallel, we can conclude that m2 is 75 degrees. This is because they are ALTERNATE angles; and alternate angles are always equal.

Now to find m1, you see that it is on the same STRAIGHT LINE as m2. What does a straight line equal to? 180 degrees! So from the degree of m2,

180 - 75 = 105

Therefore, m1 = 105 degrees, and m2 = 75 degrees

Hope this helped!
